Are these actually labeled as Vegan? What do the companies use as adhesive? Most glues/adhesives use products derived from animals. And what about the production process? How eco friendly and vegan is the manufacturing? The majority of makeup brushes available are synthetic fibers and plastic or wood handles which would be considered vegan.

As a professional make up artist, I have used Aveda brushes for 20 years. Some of them have lasted that long, just shampoo and let air dry. Love them and would love to try some of these other eco brands.
